文章在综述表面活性剂驱油发展的基础上，提出了驱油用表面活性剂的要求，并针对当前常用驱油活性剂种类进行了详细介绍，阐述了通过表面活性剂提高石油采收率的机理。最后，作者认为表面活性剂驱的发展趋势包括：（1）进行两种或两种以上的表面活性剂的复配，提高表面活性剂的性能。（2）开发在高温、高盐、低渗透等苛刻条件下的新型表面活性剂。（3）研制出经济实惠的表面活性剂和驱油体系是关键。

Summary of development of surfactant oil displacement in firstly, the paper described requirements of surfactant in improving oil recovery efficiency, and introduced the kinds of surfactant oil displacement detailed, then showed the mechanism of oil recovery efficiency improved by surfaetant. Finally, the author suggests that surfactant research trends including： （1） two or more of surfactant compound to improve the performance of the surfactant; （2） To develop new surfactants in the harsh conditions of high temperature, high slat and low permeability; （3） To develop affordable surfactants and oil displacement systems is the key.
